Original Entity Data gets overridden by the change set

Description

When changing data in an entity, the UnitOfWork will call computeChangeSet on a flush event. If there is a changeset, the original data ($this->_originalEntityData) gets overridden by the new data. However, the _originalEntityData should hold the original data, that was present at the time the entity was reconstituted from the database. This does no longer hold now.

I think this can simply be fixed by commenting this line, however I do not know of any consequences this may bring with it:

$this->_originalEntityData[$oid] = $actualData; (in computeChangeSet, after if( $changeSet ));

Anyway, I ran into this problem while trying to retrieve the original data at the onFlush event of an update.
